Bug#782069: initramfs-tools: Required format of LVM volume names not compatible with manpage for lvchange
Package: initramfs-tools
Version: 0.119
Severity: normal
The man page for lvchange states that the --activate option
[quote]creates a symbolic link
/dev/VolumeGroupName/LogicalVolumeName
pointing to the device node. ... All software and scripts should access the
device through this symbolic link ... [/quote].
Building an fstab following this advice can lead to an unbootable system,
because initramfs requires LVM volumes to be named
/dev/mapper/VolumeGroupName-LogicalVolumeName
instead, thus not activating LVM volumes of the form
/dev/VolumeGroupName/LogicalVolumeName
and thus rendering the system unbootable because the system drops into the
emergency shell.
While it is possible to resume the normal boot process by manually activating
the required LVM volumes (using "/root/sbin/lvchange -ay
VolumeGroupName/LogicalVolumeName" in the emergency shell), this is not
obvious.
A preliminary solution could be to add a strong reminder to the template for
/etc/fstab to only use the form
/dev/mapper/VolumeGroupName-LogicalVolumeName
for LVM volumes.
